New MH ballast?

I am looking to upgrade my MH reflectors soon and switch to SE Radium bulbs.
I am running 400W Hamilton DE in reefstar pendants now. I would like stick with the 400s. One of the Hamilton ballast is going bad so I would like to change this pulse stat ballast out with one I can use in the future with both the DE and SE bulbs until I can get new reflectors. I would like to have a ballast that will run anything I put in.

Will this work? Sunlight supply’s Lumatek or is there something better that will fit my needs for the future upgrade. Also any Input on reflectors would be grate also.

Thanks JB.

I personally like Coralvue ballasts. I know they will run almost everything. They are electronic. You can also get them in a dimmable form witch is really cool!

That is too much for me, I would like to buy new equipment with a warrantee.
Besides he gets to chose who he wants to sell to.

A pulse start will run anything you put in it. single or double end.

I would recommend coralvue dimmable. Great ballast and wonderful customer service if you ever need them. I run radium bulbs now and the color is fantastic. You will need to change the bulbs out every 7 months though.

because after 7 months the bulb is done...stick a fork in it....toasted. Will start to grow algae. The bulb is designed to be ran at 360w so if you run it at 400 it reduces it's life. If you chill the wattage down you may be able to get more time out of it but i've not done that just yet. Working on it now though, will have results in another 7 months.

Never experienced any algae growth due to a bulb. I did see a drop in par after 12 months of use but it really was not that bad. I was over driving them big time with 430 watt HPS ballast.

I have a major problem with the "algae growth" claims, algaes being photosynthetic need PAR (photosynthetic active radiation) to grow, same do our beloved corals.
Now why would an old bulb all of a sudden emit more par stimulating algae growth???

I'm not saying it didn't happen by any means but I know where 16 1year old plus radium 400 watt bulbs are being used and there is no algae growth taking place.

color spectrum shift, old bulbs shift color...not all colors you can see. I get brown algae on my sand, not much but it goes away when i change bulbs. I've got a old USHIO 2Ok 150w i can send you to check out what i mean, it grows all kinds of algae. It's over a year old too.

I don't want to de-rail this thread, sorry if i have already.

Plants don't see colors neither - all they care for is PAR radiation, so technically an algae outbreak states that HIGHER PAR are emitting, something any PAR meter will prove wrong.
And if it would - corals would grow better, too.

I just need someone to explain it to me - the statement "old bulbs grow algae" doesn't do it for me...

my Nano actually catches about a 2 hour "sliver" of real sunshine... guess what.. HAIR ALGAE is starting right where the sliver of sunshine hits

my big tank has been basically HA eradicated thanks to massive magnesum injection and Cliff... now have to do the same in the nano

I have to disagree that plants don't care about spectrum, This is why its important to use certain kelvin ranges to grow macro's. PAR is the closest measurement available to us on what our corals use for growth but there are still effects with spectrum that go beyond the fact that a higher kelvin bulb typically produces less PAR. Typically bulbs get more white or yellow with age actually lowering the kelvin rating working there way toward the 6000k range recommended for macro's
